In 2019,Zeitschrift fuer Kristallographie – New Crystal Structures included an article by Xing, Ai-Ping; Zeng, Dai; Zhang, Shu-Ling; Wei, Jun-Jun; Guo, Da-Feng. Computed Properties of C7H7N3. The article was titled 《Crystal structure of 2-((1H-benzo[d]imidazol-2-ylimino)methyl)-4,6-di-tert-butylphenol, C22H27N3O》. The information in the text is summarized as follows:
C22H27N3O, monoclinic, P21/c (number 14), a = 18.4984(4) Å, b = 11.4221(3) Å, c = 9.79600(19) Å, β = 90.9652(19)°, V = 2069.51(8) Å3, Z = 4, Rgt(F) = 0.0605, wRref(F2) = 0.1773, T = 293(2) K. In a typical experiment 2-aminobenzimidazole (1.3315 g, 10 mmol) and 3,5-bis(1,1-dimethylethyl)-2-hydroxy-benzaldehyde (2.3433 g, 10 mmol) were mixed in 25 mL ethanol and refluxed for 3 h. When the solution was cooled to room temperature, a light yellow solid was obtained. Crystallization from methanol at room temperature gave the title compound as colorless crystals of good diffraction quality. The experimental process involved the reaction of 1H-Benzo[d]imidazol-2-amine(cas: 934-32-7Computed Properties of C7H7N3)
1H-Benzo[d]imidazol-2-amine(cas: 934-32-7) can be used in the hydrolysis of a choline carbonate. It was also used in the synthesis of imidazo[1,2-a]benzimidazoles.Computed Properties of C7H7N3
